Although we know a lot about the world, it is a fact that there are many secrets that have not yet been discovered. Scientists continue to work to uncover these secrets. One of the areas at the center of the studies is the past of our planet.
Studies to find out what is under the Earth’s crust that we see also require revealing what lies deeper. For these studies, minerals, especially on beaches, are examined by using lasers thinner than a human hair, instead of giant excavation machines.
4 billion year layer in Western Australia
A 4 billion year old piece of land under the western part of Australia has been discovered. Although it is not important that the soil discovered here is just old, it is noteworthy that it played an important role in the geological transformation of the continent over the past 4 billion years.
Thanks to this study, we may find new clues about how life arose on our once-living planet. According to the scientists, thanks to this expansion in the crust, the stone structures were blended with new materials from the deep and mixed with the first crustal samples. The found specimens also managed to protect themselves from the natural events that led to the formation of mountains.
It is possible to look at the surface and understand space.
It is not easy to understand what is under the earth’s crust and to reveal its past. For this, first of all, it is necessary to find a suitable sample. The discovery in Australia is of great importance in this sense. Thanks to the sands evaporated by laser and separated into component materials, it is possible to examine what kind of structure emerged in which region and due to which conditions.
Scientists also aim to make it possible for us to understand how planetary crusts form and how they can transform over time, thanks to this discovery. Thus, it will be possible to evaluate the possibilities of other planets in space to host life.
